[Solved] JBL T110 Headphones: One Handset Works on Laptop, Not on Phone - Lenovo 320-15ISK Issue

Good day.
Recently, I connected JBL T110 headphones to a laptop and one handset works and the other does not work, but it works normally on the phone. The balance is good (the same) I tried mono and stereo, but it didn't work. I've been sitting here for quite a few hours and I can't solve this problem.

Hello. And you looked at this plug, after all, these headphones have a microphone and can be swapped wires on the plug and do not match this model?

But I don't understand what you mean PITERRR. The laptop has one plug and headphones too.

Yes, but whether these headphones have not replaced the wires or the leads to the speakers are somewhere else as in the phone.

And I don't know that. And how can you check it ??

Wait, PITERRR, I'll check on another laptop and write you.

Works on another laptop. I do not know what to do. I have already uninstalled drivers and installed about 10 times.

It is strange that the headphones do not work, since there is a different plug than in the laptop.

These headphones have 4 poles TRRS



and in a laptop there is probably a standard 3-pole TRS socket for an adequate plug



You can buy an adapter.

EDIT.

1. Sometimes the plugs from different manufacturers differ slightly in length, and just insert the plug "not quite" but so that in the socket "something" surprises. If the plug puts a lot of resistance when inserting, do not force it, as this may damage the socket.
2. The "headphones + microphone" set with a four-pole plug plugged into the three-pole "regular" stereo socket will work as the headphones themselves. The microphone will be shorted to ground and will not work. In this case, also remember the things described in point 1.

Unfortunately, I am green in such matters. So what should I do to use headphones normally?

Check the resistance between 1-4 and 2-4.

Unfortunately, I do not have a tool to check it on the Internet, there is nothing.

If you have separate headphone and microphone sockets in your laptop, you can buy a suitable adapter for a few zlotys:


The headphones plug into the jack on the cable, and the green plug into the laptop's headphone jack.

@DajanPC This laptop has one headphone jack with a microphone?

Yes, there is one nest.

It's a lime. The adapter I gave is unlikely to help.
In the case of TRRS, there is a free American on the market - each manufacturer has its own standards of using contacts.

You can't handle it yourself, you have to ask someone to assemble the appropriate adapter.

@DajanPC So without measuring the resistance you will not know where the right channel is and where the left channel is. You can borrow headphones with a microphone typically for computers with such a socket whether there is sound in both two channels or a regular 2-wire + adapter for one plug.

Here you have different types of plugs and connections maybe one of them fits

So lime?

Lipa - no, you need the right headphones for this laptop model.

All right. Thank you. Subject to close.
